Question 1016698
Let {{{ p }}} = the price that the retailer
should mark the sunglasses
------------------------
A selling price that gives a 35% profit
on his cost would be:
{{{ 1.35*80 = 108 }}}
--------------------
{{{ p - .2p = 108 }}}
{{{ .8p = 108 }}}
{{{ p = 135 }}}
The retailer should mark them at $135
-------------------
check:
{{{ 135 - .2*135 = .8*135 }}}
{{{ .8*135 = 108 }}}
{{{ 108 = 1.35*80 }}}
{{{ 108 = 108 }}}
OK
